Actually soldering the wires together may also introduce error voltages.
The trick is to have identical errors in each wire so they balance out.

That's why they use dual-pole switches when monitoring multiple EGT/CHT's with one meter.
As soon as you have two different metals in contact you have a termocouple point with it's resulting voltage.
I guess if you twist the (identical metal) wires together to create the electical connection between them and just use the solder as a method of securing the connection, there won't be an error voltage.

Great, NOW you tell me :-)  I may look into this, but for now, they'll just hang around in a loop when not in use.

 

Thanks,
